There is a large number of literatures about routing and dispatching plans for automated guided vehicle system (AGVS), however a small fraction of these works dealt with dynamic characteristic of this kind of scheduling problems. Current paper surveys a real time strategy to responding requests for supposed material handling system in the plant. We arranged this designing on a preplanned system where all data are known before the constructing routes. An improved ant colony optimization (ACO) is applied in order to find the shortest route path as new solicitations happened. We explore ACO initially for static version of the problem, …

Applying Group Theory For Solving Machines’ Turnovers With Capital Budgeting Approach, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati, Napsiah Ismail

Hannaneh Rashidi-Bajgan

Applying and utilizing technology in modern manufacturing systems needs to update and upgrade facilities repetitively by efficient ways to stay with great productivity along efficiency. Capital Budgeting Problem (CBP) is one of the most important issues in decision making about capital in manufacturing management; CBP determines the best investments in capital goods such as new plans, replacements, research development projects and other worth pursuing authorization subjects. This problem deals with the amount of revenues as the result of investing in the previous periods in order to maximize the amount of Net Present Value (NPV) on the decision time. Making discussions …

Hannaneh Rashidi-Bajgan

A plant layout study is to analyze different physical configurations for an industrial plant. The warehouse layout problem involves allocating several different product types to certain areas of warehouse so that the cost of material handling from docks of the warehouse can be minimized. The layout of a warehouse may need to be change to accommodate new product lines or to add greater flexibility to the warehouse operations. To ensure the success of the project, a detailed planning process should be followed. Regarding to above Decision Support Systems (DSS) are developed to help company’s personnel, modify the configuration of warehouse …


A Multiobjective Genetic Algorithm For Fuzzy Time Windows Vehicle Routing Problem, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati Jul 2010

A Multiobjective Genetic Algorithm For Fuzzy Time Windows Vehicle Routing Problem, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati

Hannaneh Rashidi-Bajgan

Vehicle routing problem (VRP) is a well-known combinatorial optimization problem, holds a central place in logistics management. In the business, transportation, time windows are not always strictly complied and the deviation of service time from specific time window determines the customer’s satisfaction level. The purpose of this paper is to pay about restriction on uploading/delivering time when time constraints are not certain. Therefore this study applies fuzzy membership functions to characterize the service level issues associated with time window violations in VRP with two goals so that minimize the travel cost and maximize the supplier’s service level. In facing to …


A Novel Approach In Determining Points Of Interactive Transportations In The Firm, Zeinab Barati, Hannaneh Rashidi-Bajgan, Elham Esmaili May 2010

A Novel Approach In Determining Points Of Interactive Transportations In The Firm, Zeinab Barati, Hannaneh Rashidi-Bajgan, Elham Esmaili

Hannaneh Rashidi-Bajgan

Partitioning is the most vital element in designing of a firm layout. Today modern working environments are intended to more use of less space which could increase more interactions between related departments. Although progress communications network has reduced the need for physical transportation but the tangible connections between different parts of a firm seems essential still. The firm is willing to reduce transfers to the minimum possible in order to prevent the vain crowd and time stuck. The purpose of this paper is to use a new approach of decision making in the location and layout of firm’s partitions. With …


A Madm Method For Office˗ Job Assignment Problem, Elham Esmaili, Hannaneh Rashidi-Bajgan, Zeinab Barati May 2010

A Madm Method For Office˗ Job Assignment Problem, Elham Esmaili, Hannaneh Rashidi-Bajgan, Zeinab Barati

Hannaneh Rashidi-Bajgan

There are different kinds of jobs in any organization; some of them have more traffic to one another, in the other words there are communicative rates between these office jobs. In this paper we want to develop an approach of analytical hierarchy process (ANP) so that enable us in assigning jobs to suitable office rooms. We suppose that we know distances between places and could predict the amount of flow movements between theses jobs and would like to minimize the distance×flow.

Benefits And Pitfalls Of Virtual R&D Teams: An Empirical Study, Nader Ale Ebrahim, Shamsuddin Ahmed, Zahari Taha

Nader Ale Ebrahim

In this paper, advantages and drawbacks of virtual teams in research and development (R&D) are studied. With the globalization of commercial practices and advances in information and communication technologies, increasing numbers of enterprises are establishing cross-functional, geographically distributed virtual teams. Virtual teams in R&D are designed to access external resources and knowledge to maximize the competitive advantage from limited labor and resources. A survey has been conducted on 210 Malaysian and Iranian manufacturing companies, aimed to investigate the characteristics of R&D collaborations and extract the main advantages/disadvantages’ factors of virtual teams. These factors can be a guide line for R&D …

Global competitiveness is one of the most important issues in manufacturing industry nowadays. Almost every company in this business industry is affected by it and they are looking for new ways to remain aligned and competitive. In recent years, the long term success of some manufacturing firms and organizations has been enhanced by their ability to bring new products onto the market at regular and shorter intervals. In order to achieve that, effective new product development requires a good integration and collaboration between internal and external participants. Moreover, in current circumstances, issues on how to effectively integrate NPD constituents in …


Virtual Integration As A Predictor For Product Innovation: A Preliminary Insight, Geraldy Dadriyansyah, Amlus Ibrahim Jan 2010

Virtual Integration As A Predictor For Product Innovation: A Preliminary Insight, Geraldy Dadriyansyah, Amlus Ibrahim

Geraldy Dadriyansyah

The intense competition in manufacturing industry has forced manufacturing firms to switch their product development approach from traditional to concurrent engineering in order to stay competitive in term of product differentiation and innovation. In order to support concurrent engineering practice, both internal and external participants contributing to product development should be located into close proximity; therefore physical integration of team becomes the key enabler of concurrent engineering. However, as the paradigm has been shifted from adopting “centralized integrated product development”, physical integration is no longer efficient and should be replaced by virtual integration. This conceptual paper intends to explore ways …

Virtual Integration As An Approach To Engender Product Innovation And Accelerate Product Development Time: A Literature Analysis, Geraldy Dadriyansyah, Amlus Ibrahim, Mohamad Ghozali Hassan

Geraldy Dadriyansyah

Global competitiveness has forced manufacturing firm, as an internal constituents, to work closer with their suppliers and customers in order to produce highly innovative product in shorter time interval. However as the business trends in manufacturing industry have evolved, centralized integration has become obsolete and no longer be efficient. Concurrent engineering methodology allows manufacturing firms to adopt a new collaboration approach called virtual integration. With the aid of computer-mediated communication, virtual integration is believed to be a promising solution to NPD collaboration issues. Therefore, this conceptual paper is aimed to seek for a new approach to engender product innovation which …
